Description

Insecticide composition {PESTICIDAL COMPOSITION}

FIELD OF THE INVENTION The present invention relates to pesticide compositions, and more particularly to pesticide compositions containing two or more pesticidal active ingredients for improved pest control.

In performing pest control, particularly insect control, two major factors that determine treatment effectiveness are: 1) immediate action against pests (in the art, "knock- down action), 2) long term action (known as "residual action"). Effective knockdown insecticides include pyrethroid, organic phosphate esters, neonicotinoids, imidacloprid, acetamiprid and phenyl pyrazole (pipronyl). Effective long-term insecticides include various forms of insect growth regulators (IGRs) such as chitin synthesis inhibitors. Current methods for achieving the desired effect include treatment repeated several times with an insecticide that has an effective knockdown action. Disadvantages of repeated treatment include: a) the use of relatively large amounts of pesticides, which may cause environmental problems; b) they are absorbed by the crops or damage the crops, so if the treatment with a valid knockdown pesticide is forbidden, There is a certain period within the ring. Using long-acting insecticides may help to avoid repeated treatments, but may not be effective against certain insects that have reached certain stages of development in their life cycle. For example, a group of pesticides known as insect growth regulators (IGRs), which generally have an effective long-term action, have little effect on adults because of their low knockdown effect.

Combinations of knockdown and long term pesticides have been reported. U. S. Patent 6,685, 954 discloses the effectiveness of fibronil in combination with the IGR of the juvenile hormone mimic group in the treatment of ectoparasites in mammals. However, no literature suggests such a combination for other purposes that are non-veterinary. In other applications, such as in the field of plants and plant matter, the problem of phytotoxicity must also be considered.

Thus, there has long been a need for pest control methods and insecticide compositions that effectively control insects by providing effective knockdown and long-term action without causing environmental, toxicity, phytotoxicity and environmental toxicity issues.

Accordingly, it is an object of the present invention to provide an insecticide composition that provides effective immediate and long term action against insects.

It is also an object of the present invention to further provide a method for pest control, in particular insect control, which provides effective immediate action and effective long term activity.

Other objects of the present invention will become more apparent from the following description.
